How to run a periodic task

[deveshaggrawal19]

I am not able to understand properly how can I run the task every fixed time such that I can make changes in the database and use application context also. Please provide guidance.

@periodic_task(run_every=timedelta(hours=1))
def periodic_run_get_reminders(**kwargs):
""" Perodic task, run by Celery Beat process
Specify whenever it should run by setting run_every
Remember to start celery beat with -B
Add you methods to make database changes here"""
